Maximum Control with the Hydraulic Flotation System

Allows the header to closely follow ground contours so you capture all the crop you grow. The return-to-cut feature uses cut height cylinders on each lift arm to easily return to the preset cutting height on each pass. Make this adjustment easily from the seat of the cab using the cut height control switches on the MultiFunction Propulsion Lever.

Hydraulic System
- Two circuit hydraulic system
  - System 1 runs knife
  - System 2 runs reel and draper
- Reel and draper circuit has a priority flow system that allows base unit to be programmed for draper and reel to sync with ground speed
- All circuits have speed sensors for in cab monitoring
Reel Arms
- 2" x 3" tubing for increased strength
- Steeper attack angle for improved crop feeding and less risk of running reel tines into knife during fore/aft operation

Transport Options

Transport - 25 & 30 Ft. Headers

Heads are available without transport system
2-wheel, removable/swing away transport system similar to DH2 Series

Transport - 35 & 40 Ft. Headers

Integral 4-wheel dolly transport system

More Acres, Less Time

Dual Circuit Header Drive provides more power to the knife drive and draper belts for faster cutting and better swath formation
40-foot draper header covers more acres in less time
Low-profile cutterbar cuts closer and cleaner to reduce harvest loss

Higher Throughput Capacity
- Wider windrow/swath opening – up to 72 inches – creates smoother crop flow
- Improved crop feeding with shallow-angled header top section
- More consistent swath formation thanks to a two circuit hydraulic system
Handles the Toughest Conditions
- Frame design with heavy-duty reel arms provides increased strength and durability
- Center drive draper belts provide consistent crop flow through the header even in high volume crop conditions
- Heavy-duty cutter bar system is more durable in rocky conditions and provides a clean cut in heavy wet crops
Basic Unit Notes
- All DH3 series draper headers are not compatible with MY2013 and prior Windrowers

DH3 Cutterbar: Cutterbar Improvements for Greater Operational Efficiency

Frame
- Tube design angled for increased strength and visibility
- Draper angle decreased from 20 degrees to 15 degrees for improved feeding and visibility
Ground Cutting and Crop Feeding
- Low profile bottom for close-to-ground cutting at lesser guard angle (7/8" at 2 degrees of tilt)
- Shallow-angled top section for improved crop feeding and reel cleaning
Cutting System
- Case IH cutting system with new raised style knife head (Shown)
- Schumacher cutting system (Shown)
- Case IH stub guard cutting system

Draper Deck
- Double V-Guide drapers for double life (reversible) and edge seal to keep trash out
- Improved deck sliding by shifting decks on UHMW blocks with added space to allow material to clean out
- Drive rollers at inside end of drapers for increased traction
Draper Deck Modifications
- Deck sizes standard between SSW and DSW units. Only difference being the end tin (2" wider on DSW units allowing opening to be made 4" smaller)
- 72" to 60" adjustable center-delivery heads
- 72" to 56" adjustable on double-swath heads
- Rear opening can be increased to 80" by removing back panel extensions
Gauge Wheel Configuration
- Coil spring-over-shock absorber
- Quick adjust design
- Provides superior ground following and float
- Increased strength in control arm
- New Crop dividers, with adjustable angle and interchageable ends (pipe and cone), are simple to install and reduce trampling.
